Study Tools for Last-Minute Cramming: What to Do With 48 Hours Left

It's two days before the exam. You've been working long shifts, the module slipped, and now there's a stack of PDFs you haven't properly opened. The plan forming in your head involves coffee, an all-nighter and rereading everything.

Let's be honest: cramming isn't ideal. Spreading study out works better, and in one flashcard study, spaced study beat cramming on the last day before the test. (Kornell, 2009) But you're not here for ideal. You're here with 48 hours, so here's how to use them well.

First, don't make it worse

The two most common cramming mistakes cost more than they give.

Rereading everything. With limited time, rereading spreads you thin and tells you nothing about what you know. You'll feel familiar with everything and still be able to answer very little.

Skipping sleep. In a survey of college students, those who pulled all-nighters tended to have lower GPAs. (Thacher, 2008) Sleep is also when your brain consolidates what you learned that day. An all-nighter trades the memories you'd keep for a few extra hours of tired, low-quality study.

Triage: decide what not to study

With 48 hours, you can't cover everything, so you have to choose:

1. Find out what's examined. Check the course outline, any exam guidance, and past papers for topics that come up again and again.
2. Rank the topics by how often they appear and how many marks they're worth.
3. Mark what you already half-know. These are your quickest wins.
4. Make your list: your top-ranked topics plus your quick wins. Accept that some topics won't get covered. This is the hardest step emotionally and the most useful practically.

Write the final list on one page and keep it in front of you. When panic tells you to go back and skim a topic you dropped, look at the list instead.

A realistic 48-hour plan

Day 1

• Morning: Do one past paper or practice exam cold, without notes, for 60–90 minutes. Mark it. Now you know where you stand.
• Afternoon and evening: Work through your top topics in 25–30 minute blocks. For each block, skim the key material, close it, write down what you remember, check, then answer a few questions.
• Before bed: Spend 15 minutes on quick questions covering everything from today. Then sleep properly.

Day 2

• Morning: Start with questions on yesterday's topics, without looking. Anything you miss goes on a mistakes list.
• Midday: Cover your remaining priority topics the same way.
• Afternoon: Do a second practice exam or a mixed question set, timed.
• Evening: Make a one-page cheat sheet of formulas, definitions and your mistakes list. Review it, then stop, and go to bed at a normal time.

Exam morning

Read your cheat sheet once. Don't start any new material.

Between blocks, take short breaks to eat, drink water and move. Keep your phone in another room while you work, because a five-minute scroll easily becomes forty.

If you only have 24 hours

The same principles apply, just compressed:

1. First hour: Triage. Pick your top three to five topics and accept the rest.
2. Next two hours: Do a past paper or practice questions on those topics, open-book if you have to, just to see the question style.
3. Rest of the day: 25–30 minute blocks on each priority topic, with recall at the end of each block.
4. Evening: Build your one-page cheat sheet, review it once, and sleep.
5. Morning: Read the cheat sheet once and go. You won't cover everything, and that's fine. A few topics you can actually answer questions on are worth more than a whole module you've only skimmed.

Then fix it for next time

Cramming gets you through an exam, but much of what you cram fades quickly, and the next module often builds on it. Once this exam is done, set up something lighter for the next one: four or five 25–30 minute sessions a week, each starting with a few minutes of recall. It takes less total time than a crisis weekend, and it's far less stressful.

Where Kora fits

With 48 hours left, the biggest time sink is making practice questions. Upload your course PDFs and Kora generates practice exams and study cards from them, so Day 1 can start with testing instead of preparation. It breaks material into 25–30 minute chunks that fit the plan above and builds cheat sheets for your final evening. When something won't click, Ask Kora answers questions from your notes.

Recap

• Cramming isn't ideal, but a focused 48 hours can still help a lot.
• Don't reread everything, and don't skip sleep. All-nighters are linked to lower grades.
• Triage ruthlessly: examined topics first, then quick wins.
• Test yourself first, study in 25–30 minute blocks, finish with a cheat sheet, and sleep. If you need practice exams from your course PDFs in a hurry, try Kora free.
